AIR PURIFIER AND BLOWER.

SPECIFICATION forming part of Letters Patent No. 731,927, dated June 23,1903. Application filed December 6, 1902. Serial No. 134,073. (No modeLTo all whom it may concern:

Be it known that I, FRED MARX, a citizen of the United States, residingat Newark, in the county of Essex and State of New Jersey, have inventedand produced a new and original Improvement in Air Purifiers andBlowers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to figures of referencemarked thereon, which form a part of .this specification.

The objects of this invention are to provide a blower which shallfurnish a supply of clean pure air; to provide means for separatelyremoving from the air passing through said blower the coarser and finerparticles of foreign matter or dirt; to secure a convenient constructionand one in which all the are inclosed or boxed, both for protection andfor ease of transportation, and to secure other advantages and results,some of which may be referred to hereinafter in connection with thedescription of the working parts.

The invention consists in the improved blower and in the arrangementsand combinations of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in

which like figures of reference indicate corresponding parts in each ofthe several figures, Figure 1 is aperspective view of the improveddevice With the front of the cabinet removed, a certain inside partitionslid to one side, and certain sieves or screens, the fancasing andconnecting-tubes being all re? moved. Fig. 2 is a perspective view ofthe fan casing. Fig. 3 illustrates one of the sieves or screens. Fig. 4is afront elevation of the improved device fully set up, a portion ofthe front wall being broken away to disclose the interior parts; andFig. 5 is a vertical section upon line m, Fig. 4.

In said drawings, 2 indicates a portable rectangular box or cabinet,which may be of any suitable size and is preferably formed of a doublethickness of boards or sheathing. Into the upper part of the interior ofthe said cabinet extends a shaft 3, which at one side porting theprojecting parts of the cabinet projects exteriorly to receive adriving-pulley 4, a bracket 5 suitably supportion of said shaft.

Within the cabineta fan 6, of auysuitable and well-known construction,is fixed upon said shaft to be rotated thereby. Said fan is disposedadjacent to the inner side wall of the cabinet and is adapted to beinclosed at its opposite side and periphery by a cylindrical casing 7,removably supported upon said side wall and with a tangentialdelivery-tube 8, as is common. Said delivery-tube 8 leads verticallydownward into a narrow tank 9, stationed in the lower part of the box 2in substantially the same plane as the fan 6 and into which the air isadapted to be driven.

The tank 9 has projecting up from its bottom a middle transversepartition 10, and on opposite sides of said transverse partition 10 areother parallel partitions 11 11, depending from the top of the tank to alower level than the top of said middle partition 10. Said tank isadapted to be partially filled with Water, into which excelsior may beput to prevent undue splashing of the water. The said water orexcelsior,or both,extend upward to or nearly to the said dependingpartitions 11 11, so that a current of air from the fan must necessarilypass through said water or watersoaked excelsior in its tortuous coursethrough the tank 9. At the opposite end of the tank from that at whichthe pipe 8 enters from the fan is a vertical delivery-tube12, whichextends upward adjacent to the periphery of said fan and through the topof the box or cabinet, as at 13. From this tube the supply of air istaken from the blower wherever it is desired to be used. Adjacent to thesaid fan 6 and tank 9, arranged one above the other at one side of thecabinet, as described, is a partition 14, which divides thecabinetvertically into compartments. other than that in which the blower andtank are stationed is provided at its lower part with a series ofhorizontal screens or sieves 15, which may be of varying degrees offineness, adapted to successively strain out ofthe entering current ofairdifferent kinds of dirt or foreign matter carried thereby. Saidscreens are preferably slid into ways 16 16 from the front of the box,and thus can be used or removed according to the kind of The compartment7 work being performed. Below said screens 15 an air-inlet tube 17extends through the side of the box or cabinet 2, and above said screensan aperture 18 in the vertical partition 14 between the two compartmentsadmits air to the center of the fan 6, as is common.

The partition 14 is preferably removable, as shown in the drawings, soas to permit of greater convenience in assembling and disassembling thevarious parts and is normally held in place against the tank 9 andfan-casing 7 by the screens 15, which thus serve as braces.

In use it will be seen that all the working parts of my improved blowerare boxed in, and at the same time if it is necessary to have access tosaid parts for purposes of repair or the like they can be readilyreached by removing the front wall or side of the box 2. Furthermore,the air taken inis first relieved of its larger and coarser particles offoreign matter by the screens 15, so that it arrives'at the fan Ginfairly clean condition. This prevents leaves and other dirt beingcarried into and through the fan and not only enables an easy removal orclearing away of such dirt when it accumulates, but also keeps the fanin better condition. After leaving the fan the air is cleansed of allfine dirt and dust by passing through the water-bath 9 and so isdelivered in a pure clean condition.

Having thus described the invention, what I claim as new is 1. In ablower, the combination of a .portable rectangular box or cabinethavinga removable front side forming a door or means of access, aremovable tank or bath arranged at one side of the lower part of saidcabinet, at fan-casing above said tank or bath and a fan therein, a ductleading from said fan-casing to the tank or bath, and a secondductleading from the tank or bath out through the walls of the box orcabinet, a movable partition arranged vertically from front to rear ofthe box or cabinet against said tank or bath and the fan-casing, andscreens extending horizontally between the side of said partition awayfrom the tank or bath and the opposite side wall of the box or cabinetand bracing the partition in place, said facing walls having slidewaysreceiving the edges of said screens, the partition and the fan-casinghaving coinciding apertures for the passage of air, and the box orcabinet. having an airinlet beneath said screens at the opposite side ofsaid partition from the tank or bath.

2. In a blower, the'combination of a portable box or inclosing cabinetadapted to open at its front, a removable water-bath at one side of thelower part of the interior of said cabinet, a fan-casing verticallyabove said bath and a fan therein, ducts leading from said fan-casin gto the bath and from the bath to the outside-of the box, respectively, aremovable partition disposed vertically from front 'to rear in thecabinet, adjacent to the said bath and fan, horizontal screens at theopposite side of said partition from the waterbath and fan, slidablysupported at their edges between said partition and parallel wall of thecabinet, and means of communication between the fan-casing and theinterior of the chamber on the opposite side of the partition from thefan and above the screens, the walls of the cabinet being apertured onthe same side of said partition below said screens.

3. In a blower, the combination of a portable rectangular box or cabinethavinga removable front wall, a removable bath arranged in the lowerportion of the cabinet adjacent to one side wall thereof, a drivingshaftextending perpendicularly through said side wall of, the cabinet at ahigher point, a driving-pulley upon the outer end of said shaft and afan upon the inner end, a fancasing detachably mounted upon said sidewall, inclosing said fan, and communicating with. the water-bath, a ductleading from said bath to the outside of the box or chamber, a verticalpartition extending from front to rear in said cabinet adjacent to thewaterbath and fan, dividing ofi? a second compartment, and horizontalscreens removably arranged in said second compartment, said compartmenthaving in its walls an aperture above said screens into the fan-casing,and a second aperture below said screens into the open air outside saidbox.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of December,l902.

FRED MARX.
